Back to the drawing board

Three hours working on a piece for a friend, and I was so focused on what I was doing I didn’t know my hand was smudging the ink. I had to step away from it because I’m so annoyed with myself.

I’ve never learned to draw without resting my hand on the paper or canvas. The tremors from years of lithium treatment don’t help (thanks a lot, psychiatrist who wouldn’t take me off the med even after I kept complaining about the shaking).

Keep my hand steady, or keep my paper clean?
